Product details

The Bresser CO² Air Quality Monitor is a precise measuring device that helps you monitor the air quality in your home or office. In a time when we often forget to ventilate regularly, this device offers a simple solution to ensure that the CO2 concentration remains in a healthy range.

Additionally, the device features a customizable ventilation alarm that reminds you in time to let in fresh air. The high precision and fast response times make the Bresser CO² Air Quality Monitor an essential tool for a healthy indoor climate.
